• Stunted Growth: Protein is essential for the synthesis of new cells and tissues, crucial for growth and development. Insufficient protein intake during childhood leads to impaired physical growth, resulting in a shorter stature than genetically expected.
• Discoloured Hair: Hair is primarily made of a protein called keratin. A lack of protein affects the production of melanin, the pigment responsible for hair colour, and can lead to hair becoming dull, brittle, and discoloured (often appearing reddish or lighter than usual).
• Edema: Swelling, particularly in the abdomen, legs, and feet, can occur due to low levels of albumin, a protein in the blood that helps maintain fluid balance.
• Weakened Immune System: Proteins are vital for the production of antibodies and immune cells. Deficiency compromises the immune system, making individuals more susceptible to infections.
• Skin Problems: Dry, flaky skin and lesions can also be symptoms of protein deficiency.
